摘　　要：采用核磁共振碳谱测试,对余吾煤业原煤和构造煤的分子结构特征进行研究。结果表明:构造煤的芳香环缩合程度相对原煤增加了58.31%,说明构造煤经历地质构造作用后,煤分子结构中芳香碳含量和芳香环的缩聚程度增加,提高了煤炭对瓦斯的吸附能力。The molecular structure characteristics of raw coal and tectonic coal of Yuwu Coal Industry were studied by carbon NMR. The results show that the condensation degree of aromatic rings of tectonic coal is increased by 58.31% compared with that of raw coal, which indicated that the content of aromatic carbon and the degree of condensation of aromatic rings in the molecular structure of coal increase after the geological tectonism of structural coal, which has improved the adsorption capacity of coal to gas.
